28 Above 28 ft, expect major flooding of the riverview avenue area and numerous homes and businesses in Mapleton. Flooding of roads adjacent to the Siuslaw River in the vicinity of Mapleton is likely. Flooding of Highways 126 and 36 will be significant.
25 Above 25 ft, expect widespread flooding, including several homes and structures in low areas of Mapleton. Many sections of Highway 126 from Tiernan to Mapleton, along with Hwy 36 north of Mapleton begin to flood. Flooding may be exacerbated during high tide.
22 Above 22 ft, expect widespread flooding of low-lying land. Several homes and structures in low areas of Mapleton start to flood. Numerous rural roads along and near the Siuslaw River will likely be flooded, and water begins to cover the lower sections of Hwy 126 at this stage. Flooding may be exacerbated during high tide.
20 Above 20 feet, expect water over East Mapleton Road. Flooding of some low-lying homes and structures begins. Flooding may be exacerbated by high tide.
18 Above 18 ft, expect minor flooding of low lying dairy land along with some structures right along the banks of the Siuslaw River in and near Mapleton.
